Latest Temple development: the map Ben gave to Rousseau/Alex/Carl shows the Temple somewhere in the island's interior, along a ridgeline, and not close to the coast. I.e. it's not near the 4-toed statue. However, it was odd that the symbol for the Temple, and the map's look & feel, was like that on the map Charlotte had of the Tempest. Were these maps made during Dharma's heyday? If so, that Widmore now seems to have been the man behind Dharma, it makes sense that he'd have access to Dharma-era maps like the one provided to Charlotte.
Question is, would Widmore have been able to get a mole onto the island, with access to communication? Or did he compromise one of Ben's people off-island, like Mr. Friendly, to acquire updates on Ben's doings on the island? How else would he have known that taking the Tempest offline was such a high priority?
